I second on visiting Venice beach! My teens loved it ! I loved it too. Very easy to check with internet and find the address and do driving directions. Trust me, if I can do it yOU can! I printed out so many driving directions maps on my trip. ha h ah
another suggestion, is just a couple of miles down on Harbor Blvd. in Garden Grove(?), Crystal Cathedral. BEAUTIFUL church structure. You can roam on your own (not on a Sunday though, there are services) or a formal tour. Church services are on TV Sundays. I don't belong to the church, but went with fam several ! years ago, and just really enjoyed the beauty.
